FIFTH-WHEEL FOR SPRING-VEHICLES.

SPECIFICATION forming part of Letters Patent No. 506,37,.dated October 10, 1893.

Application led April 5,1893. Serial No. 469,098. (No model.)

To all whom. t may concern:

Be it known that I, AUGUST SCHUBERT, of Oneida, in the county of Madison and State of New York, have invented new and useful consists in an improved construction and com,

bination of parts hereinafter described and specifically set forth in the claims.

In the annexed drawings Figure lis a plan view of the front running gear embodying.

my invention in connection with a single cross-spring and two reaches. Fig. 2 is a side view of the same. Fig. 3 is aplan view showing my invention in connection with two cross-springs and a single reach. Fig. 4 is a side view of the latter. Figs. 5 and 6 are enlarged pla-n views of the two circle-plates of the upper fifth wheel designed for a single cross-spring.4 Figs. 7 and 8 are plan views of the circle-plates of the upper fifth wheel designed for duplex cross-springs. Fig. 9 is a horizontal section of the lower fifth wheel taken on line 0c, 0c, in Fig. 10 andvshowing its connection' with a single reach. Fig. l0 is a vertical longitudinal section on line y, y, in Fig. 9. Fig. 11 is a plan View of the lower7 fifth wheel connected toa doublereach. Fig; l2 is a vertical longitudinal section on line z, z, in Fig. 11. Fig. 13 is a front view ot' the'front axle with my improved ifth wheel mounted thereon, and Fig. 14. is a vertical longitudinal section on line U, U, in Fig. 1.

. Similar letters of reference indicate correspending parts.

A- denotes the front axle of a vehicle, which axle may be of any suitable shape and may have either a single elliptic cross-spring O mounted on it as represented in Figs. 1, 2, 11 and 12 of the drawings, or have two semi-elliptic springs OO hung on it asy shown in Figs. 3 and 4. of the drawings.

R- represents the reach which may also be either single as shown in Fig. 3 of the drawings, or double as shown in Fig. l. Said reach or reaches I couple to the front running gear by the following devices: To the top and bottom of the axle are rigidly secured the metallic arms-hand -'h, the upper arm he-"- being formed with a saddle -sby which it rests upon the axle, in case the duplex spring -O-O- is hung on the axle at opposite sides thereof, but when the single cross-spring is mounted upon the axle the said saddle rests uponthetop of the lowerhalf of the spring as shown in Fig. l2 of the drawings. The saddle is rmly secured to the axle by means of clips -t"z"-. To the rear end of the arm 1his pivotally connected the reach or reaches -R- for which purpose I prefer t0 form the rear end ofthe said arm with a socket -ywin its under side and with the top-circle plate -jconcentric with said socket, and to the top of the wooden reach I fasten the rne-` tallic strap -Z'- which has the hub -kand lower circle-plate -j formed integral therewith or rigidly attached to it. Said hub entering the socket -j. Directly under the hub 7cand axially in line therewith is a socket -k'- also integral with the strap -Z- and into this socket is inserted a hub -cformed on the rear end of the arm -h-. The aforesaid hubs are provided with a central vertical orifice through which the kin g-bolt -Z- passes. To the upper arm -h- I attach a supplemental safety coupling -`lconsisting of a metallic strap or rod extending lengthwise of the said arm and provided at its rear end with an eye -,Z through which they king-bolt passes. This safety coupling I vprefer to make adjustable to take up the Wear of the eye -Z-, and for this purpose I form the arm -hwith a longitudinal cavity -mfor the reception of the rod said cavity terminating with a perforated ear -'mon the front end of the arm -hand through this ear protrudes the end of the rod -Z which is screw threaded and provided with a nut 11.- which bears on the front of the arm as illustrated in Figs. 9 and lO of the drawings; By tightening said nut the opposite end of the rod or safety coupling -lobtains a firm hold on the king-bolt. said king-bolt and in line therewith is the center of another fifth wheel by which the" running gear is pivotally connected to the body-B. This latter fifth-wheel thus has its pivot likewise back of the axle. It is support- Above the afore- IOS the rear circle by means of alongit'fudinal tie dpreferably formed in one vpice therewith, and the two top circle-platesS-.iaV-and are likewise united by a longitudinal tie -CL To maintain the two large'jcircleplates -ct-ain proper contact with-each other I bolt to the top of the saddle fafa lip or tongue -O- which laps onto a rabbet, r, in the top of the top-circle-plate The rear end of the lower tie -d-, is pro;-A vided with a rigid upward projecting hub', -owhich enters into a socket -o ong.v the under side of the upper tie cl-said hub and socket being axially in line with the.; lower king bolt -Z- and constituting the pivot upon which the two circle-plates -af-f and -bturn. These circle-plates and ties I preferably form of malleable cast iron, and' the adjacent sides of the large circle-plates@A face with steel wear-plates. The rear upper circle plate -bis also cast with a transverse bar -gto which are tied the endsfof the upper large circle-plate -aeitherl by the latter being formed integral with said bar, as shown in Fig. 7 of the drawings, or by extensions -ttW-amof the steel linings riveted or bolted to the ends ofthe bar -gas represented in Figs. I and 5 of the drawings. On a vehicle having a single spring -C- over the axle as shown iny Figs. l and 2 of the drawings, the large circleplates are entirely back of the spring and are supported thereon by the saddle s as before described. In this caseI form the lower arm or tie -cZ- with a depression -dand from the rear lower circle plate -bwith forwardly and downwardly extending arms -e-e-, and upon the free ends of these arms and upon the depressed portion of the tie -d- I fasten a cross-bar -gto the ends of which I firmly secure the ends of the extensions am-amof the large lower circle-plate Q. Through the center of the before described hub-0- and socket -opasses the king-bolt -othe lower end of which passes through a steel or wrought iron strap --tfastened to the under side of the longitudinal die -dto reinforce the same.- The king-bolt is provided with the usual head on its upper end and with a nut on its lower end and thus ties the aforesaid parts together. To the top of the cross-bar gand to the top of the front or large circle plates are bolted two wooden bolsters or cross-bars -D--D- which are fastened to the under side of the body 13. The described ifth-wheel is thus hung to the body.

What I claim as my invention is- 1. In combination with the front axle, bod and cross-spring or springs mounted on said axle, a iifth wheel having its pivot back of the axle and composed of large circle-plates in front of its pivot and small circle-plates at the rear of the pivot and supported by said large 4plates upon the spring or springs, and cross-bars fastened on the top of said iifthwheel and to the body respectively over the pivot of the fifth-wheel and over the front portion thereof, as set forth.

2. In combination with the frontaxle, body and cross-spring or springs mounted on said axle, the fifth-wheel consisting of the large circle-plates -a-a-, small circle plates -b-b'- cross-ties g, g and thelongitudinal ties -cZ-CZ, said fifth-wheel being mounted with its large circle-plates upon the spring or springs and the small circle-plates hung to the body back of the axle, as set forth.
